TCP Congestion Control Over HSDPA: An Experimental Evaluation

In this paper, the authors focus on the experimental evaluation of TCP over the High Speed Downlink Packet Access (HSDPA), an upgrade of UMTS that is getting worldwide deployment. Today, this is particularly important in view of the "Liberalization" brought in by the Linux OS which offers several variants of TCP congestion control. In particular, they consider four TCP variants: TCP NewReno, which is the only congestion control standardized by the IETF; TCP BIC, that was, and TCP Cubic that is the default algorithm in the Linux OS; Westwood+ TCP that has been shown to be particularly effective over wireless links.
